You need to understand the processing model.

XSLT is used to generate HTML from the XML.

Then the user interacts with the generated HTML and Javascript gets invoked to process the resulting events.

By the time the Javascript executes, the XSLT has finished its job and is no longer active.

If you want XSLT code to respond to user input, you can do this, but it involves invoking the XSLT transformation from the Javascript code that handles the user event. This doesn't seem to be what you are doing.

Hello, this is my first post and I am somewhat new to XSL. I am trying to do the following:

1) Use XSL to parse an XML file and build an HTML table of data retrieved from the XML file.
2) I am using an HTML5 localStorage variable to determine which "type" of user the user selects from a previous combo box. Once selected in the combo box, this variable is written out with JavaScript.
3) My XSL template will check this variable and parse the XML according to what "type" of user is selected.

Here is the XLS headers I am using:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl=""; xmlns:set=""; exclude-result-prefixes="set">

And here is my dream code:

<xsl:for-each select="user[@type='JAVASCRIPT_VARIABLE']">

I can't get the syntax for the above line of code to work. I have the JavaScript working alone. I have the XSL working when I hardcode JAVASCRIPT_VARIABLE to be equal to the userType that is stored. But I can't get the XSL syntax right to allow me to swap in a JavaScript variable into a line of XSL code.

This works fine:
<xsl:for-each select="user[@type='novice']">

Basically, I need to replace "novice" with whatever the JavaScript function returns. It could be novice, advanced, or expert.

Any ideas? Thank you in advance for your help. I couldn't find anything in the archives that worked. Trust me, I am on day three of trying to fix a single line of code. :)
